Helsingborg's AGRETATOR was assembled under the title DEMISE in 1990, initiated by the erstwhile GOD B.C. pairing of guitarist Pierre Richter and bass player Jesper Granath. Pulling in drummer Peter Wildoer, the group cut a demo 'Prophecy' in 1991. Both later addition to the ranks, guitarist Christofer Malmström, and Wildoer had also been involved with eighties Power Metal band ZANINEZ. A second session, entitled 'Visions' in 1992, then secured a deal with Crypta Records for the 'Delusions' album. However, at this juncture the group discovered the existence of the US based DEMISE and duly switched title to AGRETATOR, being a compromise on two favoured name suggestions 'Aggressor' and 'Agitator'.

AGRETATOR subsequently issued a self-financed EP 'Distorted Logic', recorded at Studiofabriken in Malmö, in 1996 before folding in 1998. The core of AGRETATOR, guitarist Christofer Malmström, bassist Jörgen Löfberg and Peter Wildoer all went on to DARKANE. Wildoer also figured in TIME REQUIEM, ARCH ENEMY, on their 1998 'Stigmata' album, and ARMAGEDDON.

An early singer, Tony Richter, joined GARDENS OF OBSCURITY and THE DARKSEND. A proliferation of other ventures included, besides being owner of 'Nekrologium' fanzine, a track record with a whole slew of extreme Metal bands such as SLIMESUCKERS, CORRUPTION, DEMISE, SLAVESTATE, ASMODEUS, SPIRITUAL TORTURE, SMÄRTA, LEGION OF DEATH and, in 1998, NOCTURNITY.
